This week in Crave: The fixer-upper edition

We start our look at the week past by extending heartfelt condolences to the victims of yesterday's horrendous Aurora, Colo., shooting, and to their loved ones. We know many of our readers have been looking forward to the opening of "The Dark Knight Rises" for weeks -- if not months -- and this senseless tragedy floats serious clouds over an event that should have been a pure geek joyfest.
